MIC45404

MIC45404 is an ultralow profile synchronous step-down regulator module, featuring a unique 2.0 mm maximum height. The module incorporates a DC-to-DC regulator, bootstrap capacitor, high-frequency input capacitor, and an inductor in a single package. The module pinout is optimized to simplify PCB layout process.

This highly-integrated solution expedites system design and improves product time to market. The internal MOSFETs and inductor are optimized to achieve high efficiency at low output voltage. Due to the fully optimized design, MIC45404 can deliver up to 5A current with a wide input voltage range of 4.5V to 19V.

The MIC45404 is available in a 54-pin 6mm × 10mm × 2.0mm max QFN package with a junction operating temperature range from –40 ºC to +125 ºC, which makes an excellent solution for systems in which PCB real-estate and height are important limiting factors and air flow is restricted.
